BOLSTER-STANDARD.

SPECIFICATION forming part of Letters Patent No. 477,650, dated June 28,1892.

Application filed March 2, 1891.

1'0 ctZZ whom it may concern.-

Be it known that I, LUDLoW G. COOK, of Minneapolis, in the county ofHennepin and State of Minnesota, have invented certain Improvements inStandards, of which the following is a specification.

My invention relates to improvements in the methods of loading,unloading, and binding logs, lumber, and heavy freights upon whateverkind of vehicle they may be placed for transportation; and the objectswhich I have in view are, first, to facilitate the loading and unloadingof such materials; second, to bind such materials so readily and firmlytogether as to largely dispense with the use of chains or heavy framesfor binding the same.

My invention consists in the constructions and combinations hereinafterdescribed, and particularly pointed out in the claims, and will be morereadily understood by reference to the accompanying drawings, in whichFigure 1 is a side viewof abolsteror rocker provided with an adjustablestake embodying my invention. Fig.2 is a perspective view of the deviceand bolster whereto the same is attached.

In ordinary use this machine forms part of a rocker or bolsterorbed-piece, of which both ends are the same, and two such rockers orbed-pieces will be used with each vehicle. These bolsters may beconnected and kept in position by sway-bars, (not shown in the drawings,) but passing through each end of the bolsters at the aperturesshown at P and moving freely therein. These rockers may be connectedwith the vehicle by a bolt passing downward through the center of each,about which they revolve.

As shown in the drawings, A represents a portion of one of the rockersor bolsters of the sled, wagon, or car. The end is provided with avertical slot parallel with the sides of the bolster or rocker andadapted to receive the end of the stake or standard 0, which is pivotedtherein by a bolt D, passing transversely through and secured in the endof the bolster. The upper end of the stake O is provided with the ringE, in which the end of a binding chain or rope may be secured. The lowerpart of the end of the bolster is cut away, as shown, to form theshoulder Lthereon, which shoulder stands inside of the line of the innerSerial No. 383,497. (No model.)

edge of the stake 0 when in its vertical position, the space being largeenough to receive the end of the lever or latch B, which is pivoted inthe block J, secured on the end or shoulder L and having the pivot-boltI for the lever B. The free end of the lever B is prevented from sinkinginto the shoulder L by the plate N, arranged thereon. As shown, thelower end of the stake O is provided with the ratchet-teeth F, the innershoulder of which teeth are all arranged to squarely engage the lever Bwhen the stake O is arranged in its several positions. By throwing upthe handle of the lever B and thereby depressing the end thereof underthe overhanging part of the bolster, the lever is disengaged from thestake O, whereupon the stake may be set at any desired angle or may beswung clear around,so that its upper end may hang clear down beneath theend of the bolster. The arrangement of the bolt D and the length of theshort or lower end of the stake (J is such that when in this positionthe teeth E will be flush with the upper surface of the bolster, therebyoffering no resistance to the rolling ofi of the load.

' When the stake 0 stands in any position where it extends above thelevel of the top of the bolster, it will be held in such position by theengagement of one of the teeth with the lever B.

I may strengthen the device and prevent wearing of the sides of the slotwherein the stake O is secured by lining the same with plates S S. (SeeFig. 2.) When in the vertical position, the inner edge of the stakerests against the upper shoulder of the slot, and the lower end of thestake being firmly held by the lever B the stake is held rigidly inposition. These stakes or standards are provided on the ends of at leasttwo bolsters or crossbeams of the vehicle, and when the same is beingloaded the stakes on the oif side of the vehicle are locked in theupright position,so as to prevent the logs or other things from rollingoff on that side. On the near side the stakes are turned down, and asthe last log is rolled upon the bolsters the stakes are turned up andlocked against them. In case the logs as first loaded should projectfarther over on one side than on the other it will be seen that thestakes on the oil": side may be lowered one or two notches to allow theload to be tained in loadinglogs or lumber by putting on the largepieces at the sides first, turning up the stakes to hold the same inplace, and then filling in the middle between the large timbers.

In unloading, the stakes on one or both sides are dropped by throwing upthe handles of the levers B, when no obstruction will be presented torolling or sliding the freight to the ground.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination, with the bolster having theslotted end, of a stake or standard pivoted therein and adapted to swingin. a plane parallel with said bolster, a lever having an end arrangedtransversely with respect to the bolster and arranged to engage thelower end of said standard, and said lever adapted to be moved out ofengagement therewith to allow said stake to be swung down, substantiallyas described.

2. The combination, with the slotted end of the bolster, of a stake Carranged therein, a bolt D for pivoting the same and passingtransversely through the end of the bolster, said stake 0 provided witha lower end having ratchet-teeth F, and a locking device adapted toengage the same, whereby said stake may be locked in any desiredposition, substantially as described.

3. The combination, with the bolster, of a shoulder L thereof, the stake0, having its lower end provided with the ratchet-teeth F, said stakearranged in a vertical slot in the end of the bolster, a bolt D forpivoting said stake therein, the locking-lever l3, pivoted on saidshoulder, and said teeth adapted to stand below the upper surface of thebolster when the stake O is swung down, substantially as described.
